0009    \brief Example class that can be used both within FWLite and within the full framework
0010
0011    This is an example for keeping classes that can be used both within FWLite and within the full
0012    framework. The class is derived from the BasicAnalyzer base class, which is an interface for
0013    the two wrapper classes EDAnalyzerWrapper and FWLiteAnalyzerWrapper. The latter provides basic
0014    configuration file reading and event looping equivalent to the FWLiteHistograms executable of
0015    this package. You can see the FWLiteAnalyzerWrapper class at work in the FWLiteWithBasicAnalyzer
0016    executable of this package.
